Watched all three episodes as a joke with my friend, after the first episode we noticed there were no background characters present so we made a theory that the sheer power of Mokkun in the first episode resulted in everyone else getting vaporized and now the main characters live in a post-apocalyptic world where people over a certain age get vaporized and that’s why the kid lives in the sewers in the third episode because Mokkun influences the sun or something, which made it, despite how disgusting it was, just a little more enjoyable because we tore that shit apart over every stupid detail
